To all whom it may concern/.-

Be it known that I, JACOB P. RUMMEL,-a citizen of the United States, and a resident of Sioux Falls, in the county of Minnehaha and State of South Dakota, have invented new and useful Improvements in Filters, of which the following is a full, clear, and exact description.

This invention relates to certain novel and useful improvements in filters, and has particular application to the construction of an article of this character adapted for general household use.

One of the principal objects of my invention is to provide a filter which shall separate and purify the water passing through the same of all animal matter, sediment, or the like.

A further object of the invention is to construct a filter which maybe easily and quickly attached to a faucet, hydrant, spout, or the like and which shall perform its proper f unctions without requiring further attention.

A further object of the invention is to divide the chamber of the filter into various sections through the medium of an improved partition 0r diaphragm and to fill or pack drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding partsin both the figures.

Figure 1 is a vertical sectional View taken through a filter embodying my improvements, and Fig. 2 isaperspecti ve view of my improved diaphragm used in connection with the filter illustrated in Fig. 1.

In the accompanying drawings, wherein I have illustrated one particular form of my invention, 1 designates the main body portion or wall of a filter or casing, which is screw-threaded, as at 2, at its upper edge to.

permit the top portion 3, which is similarly "ing solid or imperforate.

extending short tubular portion or neck 5,

having at its upper end a flange 6, the interior wall of said neck atsuch flanged portion being threaded, as at 7, to permit the filter to r be attached by said neck to a faucet, spout,

or the like. The bottom portion 8 of said casing is provided with an opening 9, preferably formed diametrically opposite to the neck of the cover portion of the filter, such opening 9 having a downwardly extending annular flange 1O surrounding the same, which flange is screw-threaded to receiveone end 11 of the discharge-pipe for the clear or purified water, which pipe is shown at 12. Over the mouth of this discharge-tube 12 is placed a of the casing. The construction of this screen 14 is more clearly shown in Fig. 2. As will be observed by reference to said figure, the

greater portion of the surface of the dia phragm or partition is apertured or orificed, as shown at 15, the apertures extending approximately two-thirds of the surface of the plate. Extending transversely of the diaphragm, immediately beneath the last row of orifices therein,is an apertured plate 16, cut or shapedto conform to the contour of the wall of the casing, such plate being hinged or pivoted, as at 17, to the diaphragm, the portion of said diaphragm beneath the hinge be- When mounted in its operative position inside the casing, the diaphragm 14: is arranged vertically, having its lower end preferably abutting against the edge of the foraminous plate 13, and the perforated hinged plate 16 is swung into a lateral or horizontal position and extends approximately parallel with the aforesaid plate 13 to a point in contact or abutment with the interior of the wall of the casing.

For the purpose of thoroughly cleaning the water which flows from the faucet through the neck 7 I fill the space between the partition and the wall of the casing adjacent to said neck with a suitable cleansing material,

stances carried by the water will be removed such as mineral wool 18, the packing extending from the neck of the filter to the base 8 thereof. Within the space on the opposite side of the partition from the mineral wool and between the top or cover of the filter and the horizontally-extending hinged plate 16 I provide a packing of filtering material composed, preferably, of charcoal 19, and in the space between the hinged plate and the foraminous plate 13 I also place a second packing of mineral wool 20, although in some instances, if desired, this space may be left empty. It will therefore be seen that each of the three chambers of the casing, which are formed by the partition described, is filled with a purifying cleansing material, which insures that injurious contaminating subfrom the same before the latter is used. The course of the water is shown by the arrows, it first passing through the neck and through the mineral wool 18', thence through the perforations 15 in the vertical partition or diaphragm', flows or percolates through the charcoal,and thence passes through the perforated hinged plate 16, through the mineral wool beneath the same, and, finally, through the perforated plate 13 and tube 12 to the point of use.

It will be evident that I have devised a filter which embodies the essential features of simplicity and cheapness, while at the same time it is extremely well adapted for household use, especially in cleaning drinkingwater.

While I have shown and described one particular embodiment of my invention, I wish it to be understood that I do not limit myself to the precise details of construction shown herein, as there may be modifications and variationsin some respects without departing from the principle of the'invention or sacrificing any of the features thereof.

' imperforate, and purifying material arranged within said casing, substantially as set forth.

2. A filter comprising a casing, having an inlet and an outlet, a perforated plate above said outlet, a partition dividingsaid casing into chambers, the greater portion of said partition being perforated, a perforated plate hinged to said partition above the imperforate portion thereof, the construction being such that the casing is further divided into chambers, mineral wool arranged within the chamber immediately beneath the water-inlet, charcoal arranged above the hinged plate, and mineral wool arranged beneath said. hinged plate and above the perforated plate covering the outlet, the mineral wool and the charcoal being adapted to cleanse the water passing through the casing, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of
